Apple has filed a patent which uses NFC and Bluetooth technology to enable person-to-person payments between iPhones or Apple Watches.
The system would enable users to choose a card from their iPhone's Wallet, enter the amount they want to pay and then authenticate it through Touch ID. A payment packet would then be transferred over WiFi or Bluetooth, with NFC used to verify the transaction and encrypt the data.
Whether the system ever makes it into the wild and how popular it would be is debatable. PayPal first let iPhone users make payments by bumping handsets together in 2010 but has seen little uptake.
Separately, Apple Pay appears set to launch in the UK next week. A leaked memo from supermarket Waitrose suggests the service will go live on 14 July.
